How about a special edition or signed copy of one of Margaret Atwood's books? You can also consider giving her a subscription to a book service that specializes in feminist or literary works, like the Feminist Book Club, which features books written by female authors. Alternatively, you could create a custom piece of jewelry for her that features a favorite quote from one of Atwood's poems or books. A perfect example could be a bracelet with a quote that emphasizes the enduring love you have for each other.
Or you can get her a star map with the date of your anniversary.
